A customer acquired six R750 servers. They must add these servers to their existing R760 iDRAC Group but are encountering errors. What is the reason for the errors?

Question

Options

• AR750 iDRACs firmware is out of date.
• BR750 iDRACs are not running the same version of firmware.
• C15G and 16G servers cannot be in the same group.
• DThe feature requires iDRAC Enterprise.

• B
  8% (2)
• C
  88% (23)
• D
  4% (1)

Explanation

Option C is correct because Dell's iDRAC Group Manager enforces a generation boundary: 15th Generation (15G) servers like the R750 and 16th Generation (16G) servers like the R760 cannot coexist in the same iDRAC group - this is a hard architectural limitation, not a configuration or firmware issue. Option A is wrong because outdated firmware on the R750s might cause other problems, but it's not what prevents cross-generation grouping. Option B is wrong because mismatched firmware versions within a generation can cause group issues, but that's not the scenario here - the core problem is the generation mismatch itself. Option D is wrong because iDRAC Group Manager is an Enterprise-tier feature, but since the R760 group already exists and is functioning, licensing is clearly not the barrier. Memory tip: Think "same generation, same group" - iDRAC groups are like generational clubs; a 15G server can't join a 16G club, no matter how up-to-date its firmware is.
